Microsoft has discovered an apparent attempt by hackers to steal user information from its South Korean MSN Web site and has taken action to repair the problem.

The attack was directed at the news section of the MSN Korea Web site, said Adam Sohn, a company spokesman. Microsoft was alerted Tuesday morning that the site had been compromised and took the site offline for a few hours to fix the problem, he said.

Microsoft has received no reports of users falling victim to the attack. The Redmond, Wash.-based software maker is still investigating the issue and has called in law enforcement to investigate and take action against those responsible, Sohn said.
